recordflowParametersInternal

Record for flow parameters with prescribed size

Extends from Modelica.Icons.Record.

Information

Data record for performance data that describe volume flow rate versus pressure rise. The volume flow rate V_flow must be increasing, i.e., V_flow[i] < V_flow[i+1]. Both vectors, V_flow and dp must have the same size.

This record is identical to Buildings.Fluid.Movers.BaseClasses.Characteristics.flowParameters, except that it takes the size of the array as a parameter. This is required in Dymola 2014. Otherwise, the array size would need to be computed in Buildings.Fluid.Movers.BaseClasses.FlowMachineInterface in the initial algorithm section, which is not supported.

Parameters

TypeNameDefaultDescription
IntegernNumber of elements in each array
Modelica.Units.SI.VolumeFlowRate[n]V_flowVolume flow rate at user-selected operating points
Modelica.Units.SI.PressureDifference[n]dpFan or pump total pressure at these flow rates
